Funny Coat – Williamson Tunnels

I was showing a group of people around Williamson tunnels one day and we all came down the stairs at the end of the tour.  As the tour group came out of the Tunnel I said to the last lady in the group,  “you’re the last one out aren’t you love?” and she said “what about the man in the funny coat?”  I said “what man in the funny coat?!” as I was sure everyone had come out of the Tunnels.   So, I waited to the group had all dispersed and I went back into the Tunnels and had a look around. but there was nobody there.  So what did she see? Was there something there or was she having me on – I don’t know…
